STOPPER FOR HOT-WATER BAGS- Specification of Letters Patent.

Patented March 27, 1906.

Continuation of application Serial No. 99 ,895, filed March 25,1902- This application filed December 9, 1905. Serial No. 291.105.

I [0 all whom trim/my concern:

Be it known that I, GEORGE H. F. SCH'RADER. a citizen of the United States, residing in the town of Greenburg, in the county of West- 5 ehester and State of New York, have invented certain new and useful Improvements in Stoppers for Hot-Water Bags, of which the following is a specification.

The present application is a continuation ofmy prior application, Serial No. 99,895, filed March .25, 1902.

My invention aims to provide an improved stopper for water-bags which shall be stronger and more easily manufactured than similar stoppers heretofore in use.

My intention aims to provide also a stop per having the various advantageous features hereinafterspecified in detail.

Referring to the accompanying drawings, illustrating embodiments of my invention, Figure 1 is anelevation of a stopper embodying my invention. Fig. 2 is a vertical seclion of thesame. Figs. 3 and 4 are respectively a section and plan of thehead. Figs. 5 and c are respectively a section and plan of the reinf n'cing-plate.

In making stoppers of the general class to which my invention pertains it is customary.

.to form them with a body comprisinga bottom plate (to which'usually a rubber washer is attached) and a screw-threaded side wall. The upper edge of the side wall is usually flanged outward and a head fastened thereon by having its outer edge crim )cd or bent under such flange. To this head the thumb-piece by which the stopper is screwed into and out of the bottle is attached. It is very diflicult to crimp heavy sheet metal around the flange of the body so as to fasten it tightly to such ilangc. in order to avoid this difliculty, I propose-to fasten the head of the stopper to the body, as before, but to make the head of thin easily-lmnt material at its edge-sand to reinforce it at its central portion, where it receives the strain of turning, and also to pr0- vide' a stiffening-ring around the central p0rtion to resist more effectually the transverse or pushing pressure to which it is subjected in use, so as to form practically ahead with a central portion of extra thickness and a surrounding ring of extra stiffness and to retain at the same time an edgeof maximum flexibility.

which is riveted or otherwise attached a rubber washer B. The head (I is attached to the upper edge of the bodyA, as shown, and the thumhnew I) is preferably a separate piece of metal attached to the head. At the upper edge of the body A there is an outwardly-extending flange E. The head C'is originally of the shape shown in Fig. 3. The head is of easily-bendable material and is stamped of such shape as to bend up the central portion G, whereby an approximately vertical stiffening-ring O is formed between the central portion and the edge I, which rests upon the flange of the body. Arcinf n'cing-plate F of approximately the size and shape of the central portion (1: of the head and closely fitting in the socket formed thereby is provided, and registering perforations ll and J are made, in the reinforcing-plate and the heau.

The parts are assembled as shown best in Fig. 2. The two ends h are passed tlirough the perforations ll and J of the head C and the reinforcing-plate I The shoulders L, formed on the thumb-piece l) near its ends, limit the position of the head and reinforcingplate on the. ends of the thumb-piece. The ends are then enlarged, preferably by swagingor riveting, as shown at M, so as-to unite the reinforcing plate, the head, and the thumb-piece rigidly and permanently to each other. The head is then set down on the body, its expanded lower portion N resting over the flange l bent or crimptal umler the flange, so as to fasten the head tightly thereto.

The plate F, fitting within the socket formed in the head, practically converts all the central portion into metal of extra thickness and by the close fit of its edges against the portion O braces the latter from inward collapse when the stopper is pushed in by pressure in the direction ofthc arrow in Fig. 2.

What I claim is 1. A stopper for hot-waterbags having a sheet-metal body with a flange at its upper edge, and a sheet-metal head with its edge crimpcd over said flange, said head being of oasilybendable metal to permit it to be crimped tightly upon said flange and being bent at its center to form a ring stiffening it against the transverse pressure to which is The portion N is then,

subjected in use and to form a central socket, a reinforcing-plate filling said socket and clamped closely to the flat central portion thereof, and a handle extending transversely to the plane of the head and having its ends passing through the central portion thereol and through said reinforcing-plate and clamping said plate tightly to the central portion of the head to form practically a part thereof, so that the head has practically a central portion of extra thickness and a surrounding ring of extra stillness whereby it is adapted to resist pressure upon the handle, and an edge of maximum flexibility to form a close joint with the flanged body.

2. A stopper for hot-Water bags haying; a sheetnmetal body A With an outward flange E at its upper edge and a sheet-metal head C having its edge N crimped over said flange, said head beingof easilyhendable material to permit it to be crimped tightly upon said flange and being bent up at its center to form a stifl'ening-ring O resisting more efl'ectually the transverse pressure 10 which it is sub jected in use, and to form a central socket, a reinforcing-plate F fitting closely in said. socket so as to brace said stifiening-ring against inward collapse and clamped closely to the flat central portion G, and a handle extending transversely to the plane of the head and having itsends passing through the central portion thereof and through said reinforcing-plate and clamping said plate to the central portion of the head to form prac-- tically a part thereof, so that the head has practically a central portion of extra thickness and a surrounding ring'of extra stillness braced against inward collapse, whereby it is adapted to better resist pressure upon the handle, and an edge of maximum flexibility to form a close joint with the flanged body.

In Witness whereof I have hereunto signed my name in the presence of two subscribing Wi tnesses.
